  • Patent number: 7839806
    Abstract: The inventive communication device for converting a baseband data signal to a baseband signal for a coaxial cable, comprises at least one first input terminal for receiving an incoming baseband data signal, at least a first output terminal for outputting an outgoing baseband data signal, a first input/output terminal for connecting to a coaxial cable for communication of a duplex signal, first rebalancing means for converting said incoming baseband data signal to a balanced input signal, subtraction means for subtracting the balanced input signal from the duplex signal to obtain a balanced output signal, second rebalancing means for converting the balanced output signal to said outgoing baseband data signal.

  • Publication number: 20030151695
    Abstract: A communication unit comprised a first and second splitting/combining device, each having terminals for receiving and transmitting a CATV signal and a data signal, respectively, means for combining the CATV signal and the data signal and a third terminal for receiving and transmitting the combined signal. The first terminals of the splitting/combining devices are interconnected through a device for extracting said CATV signals and each of the second terminals is connected to a switch controlled in such a way that the second terminals are either connected to each other directly or connected to a connection device for connection to a computer. The data signal can bypass flats desiring no data connection. Also, the communication unit may be implemented in two parts: one wall mounted part and one adapter connectable to the wall mounted part and comprising the connection unit, which is needed only where a data connection is wanted.
